1. Why is ceph df not always showing 'units' G M k

2. Why is iscsi-images showing 37GB, while it should be 30GB? And why 4 
objects instead of 3?

[@c01 ~]# rbd ls -p iscsi-images
test
[@c01 ~]# rbd info iscsi-images/test
rbd image 'test':
        size 10240 MB in 2560 objects
        order 22 (4096 kB objects)
        block_name_prefix: rbd_data.1bfcc12ae8944a
        format: 2
        features: layering, exclusive-lock
        flags:
        create_timestamp: Sat Jul  8 14:20:17 2017
[@c01 ~]# ceph osd pool get iscsi-images size
size: 3
[@c01 ~]# rbd snap ls iscsi-images/test
[@c01 ~]#
